![]() HV derived from an oscillator running on 24V ( + ferrite core tranny and rectifier ). No reason it oughtn't work on solder fumes. The demonstration I have seen is a filter box about the size of a shoe box getting filled with cigarette smoke, the volume is recirculated through the filter usinf a small ( computer size fan) and within 10 to 20 seconds the air is clear and the media reeks of tobacco smoke. When energised the effective filter density goes up trapping particles and causing them to adhere to the media fibres ( electrostatics). With cold weather approaching, many of us are having to work inside which means we need to. The midle wire mesh is connected to the other side of the HV supply. EASY DIY Welding Workshop Ventilation Fume Extractor Done CHEAP. ![]() The outside layers of wire mesh are joined together and connected to one side of the HV supply. So we are talking interleaving the media between wire mesh. It consists of a high voltage DC source ( perhaps 1KV DC) and a three layers of coarse metallic fly wire screens with two layers of very coarse glass fibre filter media. Quote from: IconicPCB on May 01, 2016, 11:27:36 pm There is a DIY electronic air filter which has some incredible performance specs. I also show the much-improved fume extractor and some tips if yo. Select the country/region, language, and currency you prefer for shopping. HV derived from an oscillator running on 24V ( + ferrite core tranny and rectifier ). In this video, I show the first (not so good) fume extractor I made and why it didnt work.

The Goal here was to make a simple to make Fume Extractor for daily use. Sharpie marks the circle to cut out of boxĬutting with a metal cutoff saw in the dremelĬircle Trimmed Out, be sure to file down all the sharp edges! So here's something COOL, a DIY Fume Extractor made completely from scratch. New-Work Square Steel Box in vise- tracing out zone to cut out with a sharpie The computer fan is also very nice- almost totally silent and moves plenty of air. I mostly just wanted to suck the solder fumes down and away from my face when I'm soldering, so even without a filter it works great for this purpose. I tried using some carbon foam filter left over from an old window AC unit, but it restricted the airflow too much. I didn't want to pay the $50 or whatever ready made fume extractors have been selling for, so I repurposed a 12v computer fan, 12v wall-wart and a new-work steel duplex box I had laying around. Make your own Fume Extractor from scratch. It works by drawing fumes through the carbon-impregnated foam and then releases fresh air back out of the box. I was tired of breathing in solder fumes- especially when soldering lots, and lots of connections for the various multi-rotors I've been working on. The Fume Extractor DIY is small, simple, and economical.
